you can use Douglas fir unfortunately big box stores sell kiln dried lumber you can use it yes but it would be better if you can get air dried also if you are careful you can get rif cut or quarter sawn if you hand pick them or or buy a wider with than you need of standard cut and rerip the wood to get quarter sawn

white oak would be real good wood but it not being quarter saw you will have trouble with warp-age some times if the boards are large enough you can split the boards and get quarter sawed or rif cut pieces out of them. the reason we use quarter sawed wood it it is less likely to warp out of shape and with the grain orientation you have less chance of the wood breaking when bending it.
